名称: Failure to Disable Reserved Bits
The reserved bits in a hardware design are not disabled prior to production.
基本信息
背景详情
引入方式
Array : The Designer and Implementer have to make a conscious choice to do this. Designers might covertly use reserved bits to debug or further develop new capabilities in production hardware. Designers might want to use these bits to debug or control/configure a future capability to help minimize time to market (TTM).Documentation : If documentation labels anything "for future use", "reserved", or the like, such labeling could indicate to an attacker a potential attack point.

| Confidentiality Integrity Availability Access Control Accountability Authentication Authorization Non-Repudiation | Varies by Context 注意： If the logic being controlled by these bits is still enabled in production, an adversary could use the logic to induce unwanted/unsupported behavior in the hardware. Adversaries with access to these bits will write to them in hopes of compromising hardware state. This type of weakness all depends on the capabilities of the logic being controlled or configured by the reserved bits. |

漏洞映射说明
依据 : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.备注 : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
